A method of verifying that defect management area (DMA) information is generated or updated normally when a disc recording and reproducing apparatus performs reinitialization with secondary defect list (SDL) conversion without certification, and a test apparatus for performing the method. The method includes performing reinitialization without certification in the recording and reproducing apparatus using a test disc with test reference information and generating test information from the defect management information which is generated after the reinitialization, and comparing reference information expected from the test reference information with the test information and providing the result of verification of the test information. Accordingly, a user can test the DMA generation or updating function of a given disc recording and reproducing apparatus within a short period of time, and the cost for producing and providing the test disc can be saved.
